In my ZPM folder, i'm showing 4,256 patches and climbing - is this right?

It looks like there are duplicates to me?

Some questions:

- Is there any way to remove all the AV patches from being downloaded? We have seperate AV servers for our AV that handle updates, so how can I remove all the AV patches from ZPM?
- Are these duplicates correct? Is there any way to do a "reset" of the patch management (ie delete all the bundles under ZPM so I can make sure its "clean"?

Running 10.2 on Windows 2003 servers (not going 10.2.1 yet due to issues I can see on the forum, and the fact 10.2 is nice and stable for now)
